Water pump Hepu or Pierburg

Pierburg is the OEM maker of the BMW water pump. Spending the extra for the BMW is ridiculous when they are 100% the same exact same pump from the same company from the same factory.

My next car I got a Hepu pump, which FCP lists as an OEM supplier. The impeller is plastic (or composite, I don't remember), but overall the part is so much nicer.

New water pump - HEPU $30.00

I'm working on adapting these water pumps to a variety of older engines. This one will be going on a Chevy LSx. The pumps support two different control schemes; one via PWM (no feedback) and one via LIN. I will be working on reversing the LIN communications and building a more sophisticated controller soon.

Hepu is OEM, never had any issues with one.

It's quality components from GermanAutoParts. Hepu WP, Conti belt, and NTN tensioner pulley, damper, and idler pulley.

The two timing belts I've done the water pump have been that design.

My original plastic impeller pump failed at 145k miles. I replaced with with a metal impeller pump (Hepu IIRC).

I had a defective hepu pump that leaked also. Only had about 20k miles on it

I would get a vdo/continental water pump. I’ve bought the all aluminum water pump from pierburg and it died in about 800 miles.
